5 SETTINGS
The control pushbuttons are typically not used for critical operations. As such, they are not protected by the control pass-
word. However, by supervising their output operands, the user can dynamically enable or disable the control pushbuttons
for security reasons.
Each control pushbutton asserts its own FlexLogic™ operand,
configured appropriately to perform the desired function. The operand remains asserted as long as the pushbutton is
pressed and resets when the pushbutton is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton
manipulation will be recognized by various features that may use control pushbuttons as inputs.
An event is logged in the Event Record (as per user setting) when a control pushbutton is pressed; no event is logged when
the pushbutton is released. The faceplate keys (including control keys) cannot be operated simultaneously – a given key
must be released before the next one can be pressed.
